Abstract

Improvements introduced in the object of the main patent No. 434,304, filed on January 31, 1975, by a process for preparing esters of dihydro-16,17 apovincaminic acid, especially for the preparation of hydroxy-2-alkyl esters of deoxyvinylamine acid of the formula : **(See formula)** in which R1 represents a lower alkyl containing from 1 to 4 carbon atoms, R2 and R3 represent, independently of each other, a hydrogen atom or a methyl group, characterized in that a chemical or catalytic hydrogenation of the compounds of general formula (II) is carried out **(See formula)** in which R1, R2 and R3 have the same meaning as in the general formula (I), R4 and R5 each represent either a hydrogen atom, or together, a supplementary bond between the two carbon atoms that carry them.
